SPECIFICATION forming part of Letters P atent No. 350,017, datedSeptember 28,1886

Application filed April 19, 1886. Selial No. 199,303. (No model.)

To all whom it may concern.-

Be it known that I, Nl-lw'rox RocEns, of .Terre Hante, in the county ofYigo and State ofIudiana, have'inventedcertain new and use 5 fulImprovements in Mechanism for Transmitting Power; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

My invention relates to devices for trans- I mitting the power derivedfrom an engine to machinery, and has relation especially to devices fortransmitting the power of a gas-engine to the axle of a street or othercar, although it may be applied with good results to many otherpurposes.

It has for its especial object to furnish a dummy which shall carry agas machine for generating a sufficient supply of gas by any well-knownprocess of generating, a gas-en- 2 5 gine which shall receive its supplyof gas from the aforesaid gas-machine, and suitable mechanism wherebythe power of said gas-engine shall be effectually utilized andtransmitted to the running-gear of the car; and with this object in viewmy invention consists in the improved construction, arrangement, andcombination of parts hereinafter fully described, and afterwardspecifically pointed out in the claims hereto annexed.

55 In the accompanying drawings, Figure 1 is a top plan view of acar-truck provided with my improved power-transmitting mechanism, inwhich is also shown, by dotted lines, the position in which thegas-generating machine and the gasengine may be placed. Fig. 2 is asectional view taken on the vertical plan a .1: of Fig. 1, looking inthe direction of the arrow. Fig. 3 is a sectional view taken on thevertical plan 1/]/ of Fig. 1. Fig. 4 is a bottom plan view of a part ofthe devices shown in Fig. 1, showing especially the shifting orreversing mechanism; and Fig. 5 is a sectional viewtaken on the verticalplan z of Fig. 1, one end of said section, on the right,

being partly broken away. Fi 6 is a detail sectional view showing thedovetail block K,

having groove k, and the blocks to which the bearings H" H are seen red,fitting in said rooves.

Like letters of reference mark the same parts wherever they occur in theseveral fig ures of the drawings.

Referring to the drawings by letters of ref erence, A A are the endframe pieces or sills of the truck of a car, a a the longitudinal beams(30 or sills, and a an inner longitudinal beam, stringer, or sill, allof which parts may be of any suitable timber, and of a size to beregulated by the weight to be borne by them, and the judgment of thecar-builder.

B B are the axles, carrying wheels I) I) and b b, and mounted insuitable bearings, I3 B, suspended in this instance below thelongitudinal beams a a by means of suitable bolts, b b. The axles B Bextend beyond the wheels, and, after the manner of the drivingwheels ofa locomotive, are provided on each end with cranks C, wrist-pins G, andparallel connecting-rods 0, whereby they are caused to rotate in unisonwith each other. 7 5

D is another shaft, mounted in suitable bearings, D, located on top ofthe stringers or sills u, a, and a. This shaft is provided with a crank,d, to receive the pitman d of a gas-engine, which maybe located ineither the position shown by dotted lines at E or that similarly shownat E, which engine receives its gas-supply from a gasgenerator by meansof suitable piping, (not shown,) which gasgenerator may be located inany suitable po- 8 5 sition, as shown by the dotted lines at F or F,preference being given to the opposite end of the car from that on whichthe engine is located, for the purpose of suitably distributing theweight and ballasting the ear. 9(

On the shaft D, I mount a double-bevclfriction-gear, G,whieh I prefer tomake of paper, although this material may be varied, which engages withtwo bevel friction-gears, G, preferably made of metal,whieh are mountedupon 9 5 the ends of two shafts, H H, lying in a slightlyinclinedposition and at right angles to the shaft 1), and are mounted insuitable bearings,

H H, as hereinafter explained. On the opposite ends of these shafts H Hare mounted Ioo bevel friction-gears I I, similar]y.. shaped and of thesame material as the gears G.

On the axle B, I mount a central double-bevel friction-gear, I, and twosingle-bevel frictiongears, I I, also preferably made of paper, which,as will be set forth further on, engage with the bevel friction-gears Ion shafts H. Each of these shafts H H is provided with a universaljoint, 71, and a longitudinal slipjoint, h.

v In order to keep the gears G G properly in contact with the doublegear G, and in order to cause the gears I I to engage the double gear 1or the single gears I I, as desired, the bearings H H and H. H, in whichboth'ends of the shafts H H are mounted, must necessari] y all be ad justablelaterall y. Each of these bearings is therefore provided with adovetail projection or rib, h, on its under side, which has a bearing ina suitable dovetail groove in a lateral] y-extendin gpedestal-block,that block on which the bearings H H are mounted beingmarked K and its dovetail groove is, and that in which the bearings H Hare mounted is marked K and its groove it. Each of the dovetailprojections h on the bearings H H is perforated to receive a rod,i,which passes through said perforations, extending far enough on eitherside to serve as abearing upon which spring 5 is coiled, and which bear,respectively, against the outer sides of the bearings H H and. nuts iand 'i, which are threaded upon the ends thereof, and serve to regulatethe pressure of the spring against the bearings, a block, i,with a plainbore, being interposed between the nut t' and the spring, the other nut,'11, (on the right hand of Figf5,) ,being, as is also the block 1'',accurately shaped to fit and move in the dovetail groove kin block K. Byscrewing up the nut 1'' there isset-up and maintained a spring oryielding contact between the gears G and G G,which can be very readilyregulated at will.

The bearings H H, as before stated, are provided with dovetail blocks tofit a groove, k, in block K, similar to the dovetail blocks shown insection in Figs. 3 and 5; but they are, however, moved by the followingmechanism: L L are two bars having, similarly to the shafts HH,slip-joints h h, and which are connected at their ends by bearings Z land Z l,

to the shaftD and axle B, respectively, so that said shaft and axle turnfreely therein. These bars L L serve as supports for the dovetail bars KK. On K,I mount a pivot, m, having a disk, on, on its upper end and itslower end squared, said, disk m being provided with two wristpins, towhich are pivoted the ends of connecting-rods m, their opposite endsbeing connected to the bearings H H by suitable pivots. the pivot m (seeFig. 4) is mounted a rod, 01, pivoted at its outer end to aconnecting-rod, a, similarly pivoted at its oppositeend to the arm a ofthe elbow-leverpivoted at n to the under side of bar L. The other arm,N, of this elbow-lever is pivoted toa rod, N, which On the lower squareend of has at its opposite end a fork, o, in which is pivoted the lowerend of a hand-lever, 0, said hand-lever being pivoted at o to a block onthe bar L. Its upper end is provided with a handle, I and spring-pawl p,which pawl, at its lower end, engages the teeth of a segmentrack, 12,secured to any stationary parts of the machinery. By means of thishand-lever and its connections the bearings H H are simultaueously movedinward and outward toward or from each other, carrying the gears I Iwith them, and bringing said gears alternately into contact with eitherthe double gear I or the gears I, accordingly as it may be desired tocause the car to run forward or back ward. This adjustment laterally ofthese ends of shafts H while the opposite ends remain stationary wouldbe impossible but for the provislon of the universal joints h intheshafts H H; hence this provision.

As it will be necessary to mount the truck on springs which are in theaxle-bearing boxes, but which I consider it unnecessary to show, as thecar moves along the track there will be a vertical movement of the shaftD with relation to the car-axle B. Every motion of this kind tends tolengthen and again shorten the distance between said axle and the shaft.To accommodate this motion is the purpose of the slip-joints in theshafts H H and the bars L L, and without such or some equivalentprovision the whole device would be inoperative and liable to be brokenat the first attempt to use it. 7 Having thus fully described myinvention, what I claim, and desire to secure by Letters Patent of theUnited States, is 1. In combination with the frame of a cartruck, anaxle mounted thereon and having the friction-gears I I, the two shaftsat right angles to the axle and carrying friction-gears I and G, saidshafts being adjustable to bring the gears G nearer to or farther fromeach other, "and having universal joints h, and the shaft D, mounted inthe frame and'provided witlrfrictio'n-gear G, as set forth.
